A man has been denied release after he allegedly fled a crash in northwest Sydney that killed a boy and left a woman and young girl fighting for life.
Police say the man was driving a Holden Commodore that hit six stationary cars as he was exiting the M2 in Baulkham Hills about 7pm on Saturday.
A 12-year-old boy in a Holden Captiva died at the scene, while a 36-year-old woman and a five-year-old girl were taken to hospital in a critical condition.
The driver of the Captiva, a 38-year-old man, was taken to hospital for assessment. They are believed to be all from the same family.
The driver of another car, a 65-year-old man, and his passenger, a 58-year-old woman, were taken to hospital with minor injuries. The occupants of another four cars escaped unhurt but the drivers were taken to hospital for mandatory testing.
"The only way to describe the crash scene is absolutely horrific. We have had to cut five people out of their vehicles," Fire and Rescue NSW Inspector Kernin Lambert told The Daily Telegraph.
"It was an extremely severe collision. People have been fighting for their lives. We have been trying to keep people alive."
One witness told the paper he believed the man had been speeding when he went into the exit.
A major police search was initiated including the use of PolAir and the dog unit to track down the driver of the Holden Commodore after he allegedly ran from the scene.
The 34-year-old man was arrested at a house at Narraweena, on Sydney's northern beaches, just before 3.30am on Sunday.
He was charged with 10 offences including dangerous driving occasioning death, failing to stop after a fatal crash and speeding more than 45 km/h over the limit.
He did not apply for bail and it was formally refused at Parramatta Bail Court on Sunday.
He was ordered to reappear again on Monday.
Meanwhile, a motorcyclist died after hitting a kangaroo near Wellington in the state's central west.
Police believe the motorcyclist fell off his bike after hitting the kangaroo on Saturday night on Goolma Road, Spicers Creek, about 36km northeast of Wellington. The man died at the scene.
